IPM v.4.10 Parsed File User GuideIPM output files report aggregated results for "model" plants (i.e., aggregates of generating units with similar operating characteristics). Parsed files approximate theIPM results at the generating unit level. This documentdefines the column headers foundin IPM v.4.10 parsed files.Field NameColumnDefinitionKey to Recurring Column ValuesYearA The model run year from which the parsed results were derived. ———Unique IdBThe unique identifier assigned to a boiler or generator within a plant. It consists ofthe Plant ID (or ORIS Code), an indication of whether the unit is a boiler ("B"),generator ("G"), or committed unit ("C"), and the Unit ID. For example, for theUnique ID "113_B_1", "113" is the Plant ID,"B" indicates that this unit is a boiler,and "1" indicates that the ID of the boiler is 1.———Plant NameC The plant's name.———Plant TypeDThe type of electric generating unit, usuallydefined by the "prime mover" and/orfuels burned. "Prime mover" refers to the machine (e.g., engine, turbine, waterwheel) that drives an electric generatoror the device that converts energy toelectricity directly (e.g., photovoltaic solar and fuel cell(s)).BiomassCoal SteamCombined CycleCombustion TurbineFossil WasteFuel CellGeothermalHydroIGCCLandfill GasMunicipal Solid WasteNon-Fossil WasteNuclearO/G SteamPumped StorageSolarTiresWindState NameE———State CodeF———CountyG———County CodeHThese four fields identify the geographic location of the unit. The State Code is theFIPS State Code, and the County Code is the FIPS County Code. New units haveblanks in these columns, while committed units have zeros. Federal informationprocessing standards (FIPS) codes are astandardized set of numeric or alphabeticcodes issued by the National Institute of Standards and Technology (NIST) toensure uniform identification of geographic entities through all federal governmentagencies.———Plant IDIA unique identifier assigned to each power plant in NEEDS. While the ORIS codeis unique for each plant, all generating units within a plant will typically have thesame ORIS code. For committed units (i.e.,those not currently operating, but firmlyanticipated to be operational in the future), the entry in this field might be a dummyORIS code assigned as a placeholder unique ID to the committed plant. (Note:ORIS originally referred to the Office of Regulatory Information Systems in the———Field NameColumnDefinitionKey to Recurring Column ValuesDepartment of Energy (DOE) Energy Information Administration (EIA) which wasresponsible for assigning unique identification codes to utility power plants.)Unit IDJ The identifier assigned to each unit/boiler in a given plant. ———Capacity (MW)KThe net summer dependable capacity (in megawatts) of the unit available forgeneration for sale to the grid. Net summer dependable capacity is the maximumcapacity that the unit can sustain over the summer peak demand period reduced bythe capacity required for stationservices or auxiliary equipment.———Fuel TypeL The fuels type selected by the model for combustion during the given run yearCoalFwasteNaturalGasOilOtherPet. CokeWaste CoalCell:boilers that combine 2-3 standard burners into a compact,vertical assembly installed on the furnace wall; multiple cells utilizedwithin a furnace.Cyclone:A special type of burner for coals with low fusion pointashes. Combustion occurs within the horizontal burner generatinghigh temps which turn the ash into molten slag. The term "wetbottom" furnace often accompanies the cyclone burner.FBC:“fluidized bed combustion” where solid fuels are suspended onupward-blowing jets of air, resulting in a turbulent mixing of gas andsolids and a tumbling action which provides especially effectivechemical reactions and heat transfer during the combustion process.Stoker/SPR:stoker boilers where lump coal is fed continuously ontoa moving grate or chain which moves the coal into the combustionzone in which air is drawn through the grate and ignition takes place.The carbon gradually burns off, leaving ash which drops off at theend into a receptacle, from which it is removed for disposal.Tangential(also referred to as "corner firing"): burners located alongfurnace corners in multiples of 4.Burner angle is off-set working inconjunction with the opposing corner burner to create a vertical,circular swirling combustion zone within the furnace.Turbo(wall fired burner): Burner design for pet coke and lowvolatile bituminous coals (Riley trademark name: "Turbo Furnace").Hour glass shaped furnace with rectangular shaped burners angleddownwards.Vertical: standard furnace (assume wall fired)FiringMThis field, which applies only to boilers,indicates the burner type and configuration(e.g., cell, cyclone, FBC (fluidized bed combustion), stoker/SPR, tangential, orvertical). A blank appears in instances wherethe firing characteristics of a boiler areunknown or the unit is a not a boiler.Wall: standard burner / furnace designused today. Circular burnerslocated on the front and rear furnace walls at multiple elevations.BottomNThis field, which applies only to boilers, indicates whether the bottom of thecombustion chamber is "wet" (i.e., ash is removed from the furnace in a moltenstate) or "dry" (i.e., the boiler has a furnace bottom temperature below the ashDryWetField NameColumnDefinitionKey to Recurring Column Valuesmelting point and the bottom ash is removed as a solid). A blank appears ininstances where the bottom characteristics of a boiler were not known or the unitwas not a boiler.Hg EMF InputsOThis field shows the combination of SO2scrubbers, NOXpost-combustion controls,and particulate matter controls that alreadyexist at a unit. The entries in thiscolumn are compiled from the "NOxPost-CombControl," "Wet/DryScrubber" and"Particulate Matter Type" fields. Together with the entry in the "Firing" and"Modeled Fuels" fields, the entries in thisfield are used for the assignment of theEmission Modification Factors (EMFs) formercury as shown in the six subsequent"Controlled Hg EMF" and "Uncontrolled Hg EMF" fields. The EMFs enable themodel to capture mercury emission reductionsthat are a function of the rank of coalburned (bituminous, subbituminous and lignite), the specific burner type, and theconfiguration of SO2, NOX, and particulate matter control devices. Consolidatingthe controls that impact mercury reductions into this field helps to insure that thecorrect EMFs are assigned to each unit. Note that EMFs are metric of the extent ofmercury emission reduction achieved bythese non-mercury controls, and do notinclude the presence or impact of mercury-specific controls (e.g., ACI).———AA Advanced Overfire AirBF Biased Firing (alternate burners)BOOS Burners-Out-Of-ServiceCM Combustion Modification/Fuel ReburningCO Combustion OptimizationDLNB Dry Low NOx BurnersFR Flue Gas RecirculationFU Fuel ReburningH2O Water InjectionLA Low Excess AirLN Low NOx BurnerLNB Low NOx Burner Technology (Dry Bottom only)LNBO Low NOx Burner Technology w/ Overfire AirLNC1 Low NOx Burner Technology w/ Closed-coupled OFALNC2 Low NOx Burner Technology w/ Separated OFALNC3Low NOx Burner Technology w/ Closed-coupled/Separated OFALNCB Low NOx Cell BurnerLNF Low NOx FurnaceMR Methane ReburnN2 NitrogenNDI Nitrogen Diluent InjectionNGR Natural Gas ReburnNH3 Ammonia InjectionOFA Overfire Airother OtherNOXComb ControlP This field indicates the NOXcombustion controls which are in existence at agenerating unit before the model is run.

Note, the model can retrofit units with control technologies at two differentstages. Retrofit Control 1 shows the control technologies installed in stage 1.Retrofit Control 2 shows the control technologies installed in stage 2. Earlyretirement, though not a control, is treated as a retrofit in the modeling and istherefore included in the column.

The model will use this retrofit if thecontrol is economical to operate, but it will not use the retrofit if the control is noteconomical. This “dispatchable” construct allows modeling behavior in areastransitioning from a more stringent to less stringent regulatory regime (for example,a state affected by CAIR but potentially not affected by the proposed TransportRule), where some operators may have economic incentive to bypass or reduceoperation of a previously installed emission control, while other operators still needto operate the control in order to comply with settlements, state rules, or other pastpolicies regardless of the status ofthe CAIR program.
